I have always taught with my classroom door closed. Officially, it’s because I have trouble with distractions, which is not a lie: Just ask my family how often I yell for quiet when I’m trying to figure out my next Quirkle move.
The unofficial reason is that I don’t really want other people watching me teach. Alone with my students, I’m a different person: I let my guard down in a way that I never do with co-workers, even people I’m comfortable with. My students get the most relaxed, funniest side of me, the side I’m not sure my colleagues would appreciate or approve of. It’s not that I do anything inappropriate – not really, anyway – but I am definitely more likely to say “booger” and “crap” when my door is closed. For that reason, I’d rather not have guests in my room.
Apparently I’m not alone. In my sixth year of teaching, our principal wanted us to learn strategies that were just being introduced by Marzano and company. Everyone got a copy of the book, we had meetings where the strategies were explored, and we collaborated on how to implement them into our lessons.
